1. A manufacturing method for an electrochemical sensor, the method comprising:
an electrode forming step of forming an electrode, made of a porous material with electroconductivity, on an insulating substrate; and
a resist forming step of coating a coating region on the electrode by a resist with non-electroconductivity in a solution state, and permeating communicating pores of the porous material with the resist, thereby adjusting a resistance value of the electrode,
wherein the coating region is a region on the electrode which is determined to have variable size and shape by adjusting percentage of printing areas in the region based on index information corresponding to the resistance value of the electrode in order to adjust the resistance value of the electrode, wherein a plurality of different resist printing patterns are prepared for the coating region, and in the resist forming step, the coating region is coated by the resist according to one resist printing pattern selected from the plurality of resist printing patterns based on the index information.
